Ockham's Razor Entities should not be multiplied without necessity. ## Background in Shimo ## • gPRC • High performance • Multi Language support • Pluggable and ecosystem ## • Service Mesh (Istio)

Golang programming patterns of Kubernetes (Controller, codegen etc) • Write your own Controller • gPRC based interface design in Kubernetes (CRI as example) • For Kubernetes users: • Effective pattern
